For testing Quartz Watches
The Analyzer Q1 is the ideal instrument for the efficient
and fast operating in the repair service, in watch laboratories
as well as for income and final control. Extensive test
and measuring futures guarantee skilled trouble shooting
on quartz watches. The measurement process is largely automated.
The multifunctional rotating/push knob allows easy and
quick parameter settings. High operating comfort is performed
by the perfect and functional placement of the
control panel as well as by the large LCD display. The chopping
rate of the motor pulses on watches with asservissement
is detected and displayed.

General
The Analyzer Q1 sets new technical standards in the analysis
and repair of quartz watches. With its new VARIO display
mode for rate measurement of mechanical watches,
the instrument, designed for universal use, is indeed a very
versatile instrument.
The operation is simple and easy to understand. Ordinary
standard measurements can be largely automated. The instrument
determines the associated parameters. For more
advanced users, measuring parameters can also be manually
selected according to requirements. The results, menus
and parameters appear on the ¼ VGA LCD graphic display.
Rate Measurement and Pulse Parameter
Along with the display of the rate accuracy, the analysis of
the magnetic signal can provide the period and the pulse
width as well as the inhibition period and the chopping
level. With this information, it is possible to determine the
efficiency of a watch drive with asservissement.
Rate and Current Measurement
The watch to be tested is supplied with a variable voltage.
Moveable probes are used as contact elements. The hands
of the watch can be observed during measurement by
means of the built-in mirror.
The display of the instantaneous values of the rate accuracy
and the total current occurs in a logarithmic scale. The IC
current, motor period, pulse width, inhibition period and
the chopping level are displayed numerically.
Pulse Analysis Motor Current
The shape of the motor pulse current is shown as a curve.
The pulse shape is an important criterion about the good
operation of the watch. Errors in the mechanical part of the
watch can be determined by comparative measurements
with a good watch of the same type. The pulse width and
the chopping level are displayed numerically.

Long-Range Recording
The Trace mode allows a long range diagram recording of
the rate deviation and the chopping level. Thereby are determined
changes in the rate deviation (e.g. caused by temperature
variations) as well as changes in the chopping level
of watches with adaptive motor pulses (e.g. caused by a
change of date) for a duration reaching 60 h.

Battery Test
Low drain batteries are automatically tested with a load resistance
matching the battery and high drain batteries are
manually tested by pressing a button.

Resistance Measurement
Measurement of the coil resistance and insulation and detection
of short-circuits and breaks.

Measurement of Mechanical Watches
The VARIO display mode provides a clear-cut and efficient
measurement of the rate and the evaluation of the rate stability.
The results are displayed in graphical form on a logarithmic
scale..
The minimum, average and maximum values of the individual
measurements since the beginning of the measurement
process are displayed under the current results. The beat
number as well as the measuring time since the beginning
of the measurement process are also displayed.

Additional Functions
–– Log printout of the numerical measurement results or
of the display contents on the Witschi thermo printer,
available as accessory.
–– Export of the numerical results and graphics (screen
contents) to a PC by means of the software AutoPrint
(accessory).
–– Real time clock. Date and time are displayed and printed
in the log.
–– The Witschi GPS receiver (accessory) allows the time
base of the Chronoscope S1 to be tested and adjusted
if necessary. For an unmatched accuracy the time base
can also be continuously synchronised.
